An entry in this table contains information about
the priority-based bandwidth of TE links. An ifEntry in the
ifTable must exist before a teLinkBandwidthEntry using the
same ifIndex is created. The ifType of ifEntry must be
teLink(200). If a TE link entry in the ifTable is destroyed,
then so are all of the entries in the teLinkBandwidthTable
that use the ifIndex of this TE link.
